通过高选择性的光环芳构化反应，合成了五种具有三苯基苯衍生物二维结构的新型二维（平面）表面改性剂。通过添加少量（< 5.0重量%）的2D表面改性剂，已经实现了通过三种聚合物膜的氧选择性渗透率的有效提高。在五种二维表面改性剂中，具有低聚环氧乙烷基团的改性剂化合物表现出最好的增强性能。这些改进被认为主要是由膜表面上的溶液选择性的改进引起的，其中2D表面改性剂累积。在某些表面改性的共混膜中，它们的PO 2-α图超过或接近Robeson（1991）的上边界线。由于所有含有二维表面改性剂的膜都显示出比相应的基底膜更好的选择性渗透性，因此它是非常有前途的。
A facile synthesis of novel five 2D (planar) surface modifiers having a triphenylbenzene derivatives as a 2D structure has been achieved by the highly selective photocyclic aromatization reaction. Efficient enhancement of oxygen permselectivities through the three polymer membranes has been achieved by adding a small amount (< 5.0 wt%) of the 2D surface modifiers. Among the five 2D surface modifiers, a modifier compound having oligoethylene oxide groups showed the best performance for the enhancement. These improvements were thought to be caused mainly by improvement of the solution selectivity on the membrane surface where the 2D surface modifiers were accumulated. In some of the surface-modified blend membranes, their plots in the P O 2-α graph were over or close to the upper boundary line by Robeson in 1991. Since all the membranes containing the 2D surface modifiers showed better permselectivities than the corresponding substrate membranes, it is very promising for the future.
